| Abstract: | Two species of Leptographium were isolated from blue-stained sapwood of Pinus khasya and bark beetle galleries in pine trees near Chiang Mai, Thailand. Based on morphological observations, these two species
were identified as L. pini-densiflorae and L. yunnanense. This is the first record of these fungi in Thailand. Leptographium yunnanense appeared to be associated with Polygraphus major.
